I have to say that for a rollover the passenger cabin is amazingly intact. Pretty sure your VX gave up its ghost to save your life. The bent frame is problematic, otherwise I'd say it was all fixable, but there are a lot more people here who know a lot more about the VX than I do. Maybe they have a different opinion.

If you do decide to part it out, I would be interested in a few items (rear headrests for one), but maybe you want to give it a few days first.
